Triptorelin is a synthetic gonadotropin-releasing hormone (GnRH) agonist. It works by initially stimulating, then suppressing, the release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the pituitary gland. This leads to a reduction in sex hormone levels — testosterone in males and estrogen in females.

Product Description:

Triptorelin is a GnRH agonist. Given continuously rather than in the natural pulses, it first stimulates the pituitary and then desensitises it, so gonadotrophin release stops and sex hormone production falls to castrate levels. The initial stimulation produces a testosterone surge in the first two weeks that can worsen symptoms in men with extensive prostate cancer, which is why antiandrogen cover is given at the start.

The three depot strengths correspond to one-month, three-month and six-month formulations of the same molecule. They are used for advanced prostate cancer, endometriosis, uterine fibroids, and central precocious puberty in children, where halting premature pubertal development preserves adult height. Hot flushes, loss of libido, fatigue and mood change follow hormone withdrawal. Bone mineral density falls with prolonged use and requires monitoring, with calcium and vitamin D supplementation.

Sourcing notes. Available from several manufacturers, with patent status varying by market. The three strengths are different dosing intervals, not different patient sizes, and each is supplied as a kit of microgranules plus a specific diluent and syringe — quotations must specify interval and include the kit. Some presentations require refrigeration. Paediatric use is a distinct, tightly specified market.

Frequently Asked Questions

In most markets they are one-month, three-month and six-month depot formulations of the same molecule. Each is a separate product with its own dosing interval.

Triptorelin is used as the acetate or the pamoate (embonate) salt, depending on the product. The salt is fixed in each product's registration, so specify it when you ask for quotes.

Triptorelin, licensed from Tulane University, was developed commercially by Debiopharm, which manufactures Trelstar in Switzerland. It is sold under brands such as Decapeptyl, Diphereline, Gonapeptyl, Trelstar and Triptodur, marketed by Ipsen, Ferring, Verity and others. Long-acting depots are harder to make than ordinary injections, which limits the number of generic versions.

Triptorelin is a synthetic decapeptide. Ask for the salt form, a Certificate of Analysis covering assay, peptide-related impurities, water and counter-ion content, the site's GMP certificate, and a DMF or CEP where your market requires one.
